(1) After recovering the residue from AASHTO R‐78 Procedure B, the sample may be annealed prior to testing to remove any excess moisture and provide for a consistent sample.

The annealing can be accomplished by placing 20 grams of residue in a 6 oz. metal container (approx. 3‐inch diameter) and heating to 163°C for no more than 15 minutes. The sample should be stirred with a spatula every 5 minutes. The sample can then be poured directly into a 25mm DSR silicone mold for evaluation.

Handling Protect emulsion from freezing Avoid overheating Avoid excessive pumping

1. Percent residual asphalt and percent mineral filler shall be based on weight of dry aggregate.

2. Reference to ISSA TB means International Slurry Surfacing Association Technical Bulletin.

3. Samples to be prepared by ISSA TB 148 Marshall Compaction only (30 blows/side) and tested in dry condition at 25°C

a. A compaction temperature of 154C has been found to be sufficient.

b. Four hours of total heating time (± 5 minutes) has been found to be sufficient to reach the compaction temperature.

c. Allow to cool and measure Bulk Specific Gravity.

d. Perform Tex T245-f once the samples have dried to constant mass in front of a fan at room temperature.

4. Prepare samples for ASTM D 8225:

a. Mix component materials and spread them approximately 2 inches thick on release paper. Allow the mixture to cure at

60C for 16 hours.

b. Proportion the material to yield proper dimensions for the test.

c. Heat the mixture to 154C for four hours (+/- 5 minutes) and compact to a minimum of 2.200 g/mL with a Superpave

Gyratory Compactor (30 gyrations).

d. Allow to cool and measure Bulk Specific Gravity.

e. Perform ASTM D 8225 at least 16 hours after testing Bulk Density.
